This paper presents a prototype of an acquisition board of electromyographic signals (EMG);an embedded portable, wireless and low cost solution. The system is composed of an EMG acquisition board, Zigbee modules and a device named GPRSx. After acquiring the EMG signal, it is sent through ZigBee wireless technology to GPRSx device. The GPRSx device sends the EMG signal to a server on the Internet by using GPRS wireless technology. Thus, the EMG signal is displayed in a graph on a remote computer. The results are very promising and may serve as a reference in studies for the biomedical area.

This paper describes the usage of the Matlab/Simulink and Ptolemy II environments as learning tools in the implementation of simulation models, which represent the decentralized multi-loop control system proposed for a fouling detection didactic platform. The platform is treated as a two-input two-output (TITO) plant with time delay, i.e., the voltage and current as the plant inputs and the flow and preßure as the plant outputs. In both the software environments, the control system is modeled as a cyber-physical system (CPS). Constructive details of each simulation model are shown, even as the main advantages and disadvantages of each learning tool are discußed and evaluated by engineering students.

This paper shows the use of PBL (Problem-Based Learning) technique as a key to learning VoIP in courses like electricalengineering and computer Networks in conjunction with open source and the public domain software called Asterisk which was used to create the scenario of the experiment and the problems presented to the students. In order to make the validation, the experiment was applied to students of Bachelor in electricalengineering and in Communication Technology System, undergraduate courses at the Federal Institute of Education, Science and Technology of Paraíba - IFPB, in the Telephony subject, with promising results. The Asterisk software was presented as a useful and flexible tool for constructing scenarios and problems for the teaching of VoIP technologies and the used approach resulted as effective for improving the attainment of the defined learning objectives.

This paper describes a system able to acquire, process and eliminate noise in continuous streams of data in real-time. The signal processing algorithms were based on the discrete wavelet transform and employ a new approach to deal with border problems, allowing to process the data continuously. The system was implemented using a DSP coupled to a digitizer through its external memory bus to guarantee deterministic behavior while maintaining some degree of flexibility in its configuration. The achieved performance and potential applications are discussed at the end of the text.
